UK terrorism police have announced an investigation into what they have called the deliberate murder of Russian businessman Nikolai Glushkov in London's south-west earlier this week.

Mr Glushkov, 68, was found dead by family members and friends at his home in New Maldon Monday night.

The Metropolitan Police's Counter Terrorism Command was placed in charge of the investigation and have since declared Mr Glushkov's cause of death as "compression to the neck", the BBC reports.

The CTC does not currently believe Mr Glushkov's death is linked to the high-profile poisoning of a former Russian spy Sergei Skripal and daughter Yulia with nerve agent in Salisbury.

The former deputy director of Russian airline Aeroflot, Mr Glushkov was jailed in 1999 on charges of fraud and money laundering.
